Guangxi Yuchai Machinery Co. Ltd. (GYMCL), the main operating subsidiary of China Yuchai International Ltd., has begun a new project to develop and produce a full portfolio of natural gas-powered engines to complement its current diesel-engine range, primarily for the large bus, mid- to heavy-duty truck, power generator, and marine engine markets. A new facility, with a capacity to produce 20,000 gas engines, will be constructed at the company’s main facility at Yulin City, Guangxi Province. It is expected to be operational in early 2013. The new facility also will undertake R&D efforts to advance production capabilities. GYMCL notes that China’s 12th Five-Year Plan targets natural gas to make up 8.3% of the primary energy mix by 2015, which represents about 9.2 trillion ft3 (260 billion m3) of gas, more than three times the consumption in 2008. According to GYMCL, the country’s major oil companies, China National Petroleum Corp., China Petrochemical Corp., and China National Offshore Oil Corp., are actively building pipelines and facilities to increase the use of natural gas.
